BLAKE3 is a very fast cryptographically secure hash algorithm, when i run this implementation https://github.com/php/php-src/pull/6358 against ext/hash/bench.php on an i7-8565U, it's competing against adler32 in performance, and it's significantly faster than every other cryptographic hash (~2.6 times faster than md5 ! and ~4.6 times faster than sha3-256) it's also the latest iteration of the BLAKE hash, which was a SHA3-finalist, more info about it can be found here: https://github.com/BLAKE3-team/BLAKE3
any chance of getting BLAKE3 supported in php? it'd be a good fit for projects seeking "the fastest cryptographically secure hash", and with Tiger having near-collisions and SHA2 being vulnerable to length-extension, i think that's currently sha3.
